No. 436,593 Claims priority, application Japan, May 21, 1964,39/49,449 6 Claims. (Cl. 348) The present invention relates to anair-cushion.

More particularly, this invention relates to a novel aircushioncomprising a pair of flat-shaped bag-like air chambers made fromair-tight as well as water-proof material and bonded to each other atleast on the upper fringes thereof, said air chambers being folded overat said fringes so as to make inner walls of said air chambers face eachother; an air cock communicating with the air chambers for regulatingthe air contained in said air chambers; and a skirt part made integralwith said inner walls and extending outwardly from the lower frin-gesthereof, said skirt part having the length substantially equal to araincoat and being seamed water-tightly down the back thereof.

An object of the present invention is to provide an aircushion which canserve, beside its own primary use, as a cushion upon which one can liereclined and also as a rain wear.

Other objects of the invention will be apparent through the followingdetailed descriptions of the invention.

In the drawings which illustrate an embodiment of this invention:

FIG. 1 is a perspective view of the air-cushion according to thisinvention;

FIG. 2 is a cross sectional view taken on the line 11-11 of FIG. 1;

FIG. .3 is a cross sectional view in part of the collapsible skirt partseamed to the lower fringes of the air chamber;

FIG. 4 is a cross sectional view in part taken on the line IVIV of FIG.1;

FIG. 5 is a side elevational view of the air-cushion as the skirt partis self-contained therein; and

FIG. 6 is a front view of the air-cushion serving as a rain coat.

In the drawings, numeral 1, 1' are a pair of air chambers each made fromairtight material snuch as rubberized cloth or thin elastic films ofsynthetic resin and each having four fringes or layers, that is, upperand lower fringes 2, 2 and front and rear fringes 2", 2". The upper andrear fringes are seamed together by suitable adhesives. An air cock 3 isprovided to the rear fringes 2" by which to pump the air into said airchambers 1, 1 simultaneously, a collapsible ski-rt part 4 being formedby a thin Waterproof material such as films of synthetic resin havingupper ends extending from and made integral with the inner sides of saidlower fringes of said air chamber 1, 1' and provided with button holes 5on the front side thereof and buttons 6 on the corresponding front sidethereof. Though in the embodiment illustrated in the accompanyingdrawings, the rear fringes 2" are seamed together and the air cock 3 isprovided thereto, said fringes may be kept unseamed and the air cock maybe provided to other fringes.

This invention, as above-described, consists in a pair of air chamberswith the fiat sides facing each other and with the upper fringes seamedto each other and a collapsible skirt part seamed to the lower fringesof said air chambers and may be utilized as a cushion in a sittingroom,in the first place, with collapsible skirt part dis posed within thespace composed between the air chambers 1, 1' and air pumped into saidair chambers 1, 1' through said cock 3, and secondly as an air pillow inthe 3,316,567 Patented May 2, 1967 ice open fields with air chambersexpanded with air and collapsible skirt part 4 drawn out and spread fullon the ground so that one may lie on the extended skirt part lengthwisewithout staining the wearing apparel, and thirdly as a rain wear, withthe air chambers half filled with air and the front sides thereof fiaredopen and said collapsible skirt part drawn out, wherein said drawn outpart serves as a rainproof apparel and the air chambers as a hood.

Also, 'the air chambers discharged of its air contents can be collapsedinto a small size and carried easily. It is significant that the aircushion which this invention provides can serve three purposesregardless of the very simplified structure comprising air chambers 1, 1folded together and seamed at the upper fringes and collapsible zkirtpart attached to the lower fringes of said air chamers.

What is claimed:

1. A combination air-cushion and head cover comprising, first and secondinner layers of material of substantially coextensive length and widthhaving one pair of their corresponding sides and their corresponding topends sealed together to form a hood opening at the oppositecorresponding sides, and an enveloping layer sealingly connectedadjacent the top ends of the respective first and second inner layersand overlying the exteriors of said first and second inner layers andextending downwardly along the respective sides thereof and beingsealingly secured around their peripheries to the respective sides ofsaid first and second inner layers to define inflatable substantiallyaligned pillow chambers on each side of said hood.

2. A combination air-cushion, according to claim 1, wherein said firstand second inner layers of material are substantially rectangular, saidenveloping layer forming substantially rectangular pillow chambers withsaid first and second layers on respective sides of said hood which arecoextensive in width and length.

3. A combination air-cushion, according to claim 1, including inflationmeans extending from the exterior of said hood into each of said pillowchambers for inflating said pillow chambers.

4. A combination air-cushion and head piece, accord ing to claim 1,wherein at least one of said first and second layers of material islonger than said enveloping layer and defines a protective coverextending outwardly from said pillow chambers for supporting the body ofa person whose head rests on said pillow chambers.

5. A combination air-cushion and head piece, according to claim 1,wherein each of said first and second layers are longer than saidenveloping layer and define a cap, said first and second layers beingfoldable in overlying relationship to also define a protective coveringextending downwardly from said pillow chambers which may be spread onthe ground alongside the pillow chambers of said hood to provide asupport for a persons body when resting the head on the pillow chambers.

6. A combination air-cushion and head piece, according to claim 1,wherein each of said first and second inner layers extend downwardlyfrom said hood and define a cape, said first and second layers havingrespective opposite corresponding sides with complementary arrangedbuttons and button holes for securing said cape.
